turbo timer install

i'm in the process of installing a greddy turbo timer on my 2g talon. i have the adapter harness but was wondering about the 3 wires that look like they need to be spliced into something up near the ignition. the book says nothing about them. and also do i need to hook up the speed sensor wire?

Im also installing a greddy turbo timer which should arrive sometime this week I found some information here I hope it helps you.
